Serial No. 495,952.

This invention relates to a machine for Winding warp threads on atapcredwarp beam and relates more particularly to the winding of a warpcomposed in whole or in part of elastic warp threads.

It is the general object of our invention to provide a machine by whichelastic warp threads may be fed under slight but substantially uniformtension to a conical tapered warp beam.

A further object of the invention relates to the provision of improvedmeans for storing the warp threads which are to be fed to the machine,and to the provision of improved means for delivering the threads to theconical warp beam at different but definitely related speeds.

Our invention further relates to arrangements and combinations of partswhich will be hereinafter described and more particularly pointed out inthe appended claims.

A preferred form of the invention is shown in the drawings, in whichFig. 1 is a sectional side elevation of our improved machine;

Fig.2 is a side elevation of certain driving connections; v

Fig. 3 is a plan view of enlarged scale;

Fig. 4 is a detail sectional side elevation, looking in the direction ofthe arrow 4 in Fig. 3; v p

Fig. 5 is a detail plan View, looking in the direction of the arrow 5 inFig. 4, and

Fig.6 is a detail sectional View of one of the thread-gripping discs.

Referring to they drawings, we have shown a winding machine having aframe in which a driving shaft 11 is rotatably mounted. The shaft 11 isprovided at one end with the machine on a handle 12 by which it may berotated and r at the opposite end with a dog 13 having a driving win 14engaging a recess in one of the heads of a tapered warp beam 15.

The opposite head of the warp beam sin1- ilarly engages a dog 16 on ashaft 17 which is rotatable in bearings in the frame 10 and is mountedin line with the shaft 11.

The beam has a shaft or gudgeon 20, the

ends of which are received in axial openings in the dogs 13 and 16. i

A feed-roll shaft 22 is mounted in fixed bearings and supports a taperedfeed-roll24, shown in the drawings as formed in three tapered sections.The ratio between the largest and smallest diameters of the three-partfeed-roll 24 is substantially the same as the ratio of the largest andsmallest diameters of the warp beam 15.

The warp beam shaft 17 is connected to the feed-roll shaft 22 bysprockets 27 and 28 and a chain 29 (Fig. 2). The surface speed of thefeed-roll and of the Warp beam barrel are substantially the same.

Presser rolls 30 are rotatably mounted in swinging arms 31 and engagethe upper surfaces of the sectional feedroll 24, and these presser rolls30 are also preferably of a corresponding taper.

The warp threads W' are preferably stored in open-top receptacles 40, asshown in Fig. 1, and are drawn upward. therefrom around guide rods 41located substantially above the receptacles 40. The warp threads TV thenpass downward around a guide rod 42 and upward around a second guide rod43 and through a comb 44.

The threads 1V are drawn from the receptacles by thread-gripping andforwarding members (Figs. 4 and 5) by which the threads are delivered tothe sectional feedroll 24.

Eachthread-gripping member 50 is pref erably formed as indicated in Fig.6 and comprises a pair of plates 52, mounted face to face on a hub 53,and each having a plurality of peripheral fingers 54. lhe fingers 54 ofeach plate 52 are bent and displaced toward and beyond the face of theadjacent plate 52, thus giving them the overlapping relation shown inFig. 6.

The fingers 54 thus provide a V-shaped peripheral groove, adapted tofreely engage an elastic warp thread and to grip and draw forward thethread at a predetermined speed.

A series of these gripping and forwarding members 50 are mounted on a.shaft ,60, rotatable in fixed bearings 61 (Fig. 1) and. provided with asprocket 62 (Fig. 2) con- The warp threads WV are drawn by the nected bya chain 63 to a sprocket on the shaft 22 previously described. Thesesprockets are so'proportioned that the peripheral speed of the members50 at their thread gripping surfaces is substantially the same as theperipheralspeed of the associated part 0f thefeed-roll 24; The severalmembers 50 progressively decrease in'diameter from one o end ofthe setto the otherso as to maintain 7 same pointfin the 'warp.

the same-ratio of feeds thrdughout the width of the warp.

Additional combs 65 and 66 (Fig. 3) are provided for guiding thethreadsW from the feed-roll 24 to the; warp beam 15.

While we have indicated a handle 12 for turning the" wa beam l5 andother con"- nected parts, it will be understood that any suitable powerdrive may be substituted; I

Having: described the con'stru'ction of our improved winding mach-inc,the operation a advaiitagesthereof are as follows:

forwarding members 50' against the uniform but-slight friction of theguide bars 41, L2 and 43 and this is the only tension placed on the warpthreads asthey are withdrawn from the contain r-s40 in which they areloosely coiled. The, tension of the threads is thus mach more uniformthan in-a construction in which the threads are d rawin from spools ina; reel, which case the size'and weight, of the spools, as well as theinertia thereof, causes wide variations in thread tension.- I e r Thewarp threads W are forwarded from the members 50 to. the feed-roll 24 atspeeds corresponding in ratio to the diameter of the feed-roll at thepoints to which the respective threads are delivered, and the threadsare forwarded at the same'rate and in the same speed ratio tothe warpbeam 15. We are thU'S'fliblO to wind atapere'd cone warp from elasticwarp threads in such a manner that all of the warp threads are undersubstantially the same" tension at the ptiint of delivery to the warpbeam.

As the amount of warp on the warp beam 15 increases, a slight increasein peripheral s eed at the surface of the beam. will be pro =du'ced,caiisin'g a slightly increased tension on the'warp as awhole, but thisincrease often'si'on' is i'elatlvely slight, due to the definitelylimitedrleng'th of a rubber warp.

Furthermore, such variations in total warp tension are not obectionable,.so'long as the tension in the different warp threads is'maintained uniform throughout. the width ofth'e war-pa p In otherwords, the important thing in winding a conical warp beam with elastic Iwarp threads is to maintain a substantially uniform tension of all ofthe Warpthreads as compared with each other at any given point in thewarp. Variations in total warp tension a're'i'eadily taken care of byusing an apron or other suitable surface friction to retard theunwinding of the Warp in the loom. 7

While the machine has advantages for general purposes, it isparticularly effective with bare rubber or covered rrubber threads,which require very careful and delicate handling to prevent widevariations in thread tension, asbetween different threads at the Havingthus described? our invention and the advantages thereof, we do not'wishto be limited to the details herein disclosed, otherwise than; assetforth in the claims, but what we claim 1s:-
